Police look for witnesses in deadly tire accident

24 hours later the mangled Chevy sits in an impound lot, providing a close-up look at the damage.

Broken glass and twisted metal shows the force with which the truck's two wheels slammed into the car.

Perhaps the most useful source of information has so far stymied investigators. The driver of the rig has not yet spoken with authorities.

Sixty-two-year old Adele Mancuso of Toms River was killed when the wheels of the flatbed-style truck came loose, went across four lanes of traffic of I-95 and crushed the top of her car.

Mancuso, who used to live in Larchmont, died instantly. Her 82-year old mother miraculously survived with only cuts to her arm.

Police say Mancuso had no time to respond.

"It's very unusual and not something you would expect if you were driving," Mallard said. "They were driving, not doing anything inappropriate, obeying all the rules. And it's just a freak accident."

Police say the driver of the 18-wheeler didn't stop, possibly unaware he lost two tires. He was stopped nearby by a witness, but investigators say he left the scene again.

Meantime, investigators are also looking to speak with at least two motorists who alerted the 31-year old driver that there was something wrong with his truck. Police say it's too soon to know whether charges will be filed.
